Gameforge’s data comes from a yearlong study it conducted, which shows 16.4 percent of non-paying users converted to paying users within the 12-month period. Additionally, the study shows 3 percent of these converted users purchased virtual currency and/or premium content in these games over 20 times during the study.

In a statement, Gameforge Payment Product Director Andreas Schulze noted his company expects to see continued conversion growth. He also said he thinks SponsorPay has positioned Gameforge to take advantage of the direction the market’s headed.

One of the biggest concerns among social and mobile companies is how to increase user conversion and increase monetization, so data like this will likely make the platform an appealing potential partner for developers. This is the second time in as many weeks that SponsorPay’s had results to brag about: Earlier this month, the company reported it more than doubled revenues in 2012 thanks to a 479 percent growth in transactions on its platform.
